摘要： This concerns a molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The aforementioned trip unit has disposed on an outside surface thereof, dials for adjustment of the thermal and magnetic tripping characteristics of the circuit breaker. The face of the trip unit also has a set of hinge regions disposed therein into which a plastic, transparent, hinged cover may be inserted. The top of the trip unit has a convenient ridge around the outside of the dial regions. The cover after insertion is rotated downward on to the face of the dial region and then moved transversely to abut one of the ridges. Both the cover and the surface of the dial region have bridged openings therein through which a single wire may be fed and locked in place with a solder lock at the ends of the wires. Thus the trip unit has a non-removable cover which covers the dial settings but, because the cover is transparent, the dial settings can be viewed.

摘要： In a circuit breaker having electromagnetic tripping device (55), thermal tripping device (56,57), and adjusting device (59-64), the adjusting device (59-64) is disposed above the thermal tripping device (56,57) in perpendicular direction to power source side-load side direction, and the adjusting device (59-64) has an arm (69) for transmitting adjusting actions from an adjusting dial (24) to a movable iron core (55a) of the electromagnetic tripping device (55), and such constitution enables to shorten a configuration in the power source side-load side direction, and enables to compensate loose-assembly or deformations of the adjusting device (59-64), and thereby initial setting for the adjusting device (59-64) becomes correct.

摘要： This device comprises means for detecting, respectively, overcharges, by means of bimetallic strips and short-circuiting, by means of mobile magnetic plates effecting independently from each other the controlling of the switching off of a circuit-breaker for the protection of a circuit. The thermal safety means operate through a mechanical power amplifier comprising a cage with uprights, a rotating catch dependent on the thermal phase-detectors and a plunger transmitting the power of a spring to effect the switching off.
